Moreover, further subgroup analyses revealed that TLR4 rs1927911 polymorphism was significantly associated with the risk of cerebral infarction in the recessive model (95% CI 0.46-0.96), whereas TLR4 rs4986791 polymorphism was significantly correlated with susceptibility to atherosclerosis among Asians in the dominant (95% CI 1.58-6.66), additive (95% CI 0.13-0.69) and allele (95% CI 1.58-5.53) models.
